man pages and programmer documentations for the socket options
SO_REUSEPORT are different for different operating systems and often highly confusing. Some operating systems don't even have the option
SO_REUSEPORT. The WEB is full of contradicting information regarding this subject and often you can find information that is only true for one socket implementation of a specific operating system, which may not even be explicitly mentioned in the text.
So how exactly is
SO_REUSEADDR different than
Are systems without
SO_REUSEPORT more limited?
And what exactly is the expected behavior if I use either one on different operating systems?
